Mentioned since the 500's, some authors considered it indigenous of the Treviso area. As it matures earlier, it was used to "soften" the Prosecco, especially in cold years. Bianchetta primarily was, and still is, grown in the Treviso area, and the work of Caronella (1788), of Zava (1901) and Dalmasso (1937), confirm its cultivation. In the past it was also widely distributed in the Adige region, and in Valsugana Valdadige, and in the name Bolzanese with white Vernaccia or Pavana.

It has abundant and constant productivity. It prefers deep and calcareous soils, with a long pruning pergola.Diseases and adversity

The long-standing commitment of Foss Marai in the reclamation of disused native vines such as Bianchetta Trevigiana has given the chance to this old grape to be an essential part of the amazing spumante called Marai de Marai.
